Ethyl Cellulose (EC)
Product Description
Ethyl Cellulose (EC) yog ib qho tsis qab, dawb-ntws, dawb rau lub teeb tan-xim hmoov.ethyl cellulose yog ib daim ntawv khi, zaj duab xis qub, thiab thickener. Nws yog siv nyob rau hauv suntan gels, cream, thiab lotions. Qhov no yog ethyl ether ntawm cellulose.Ethyl Cellulose EC yog soluble nyob rau hauv ntau yam ntawm cov organic solvents. Feem ntau, Ethyl Cellulose EC yog siv los ua ib qho tsis swellable, insoluble tivthaiv hauv matrix lossis txheej txheej.
Ethyl Cellulose EC tuaj yeem siv los npog ib lossis ntau cov khoom xyaw nquag ntawm cov ntsiav tshuaj los tiv thaiv lawv los ntawm kev cuam tshuam nrog lwm cov ntaub ntawv lossis nrog ib leeg. Nws tuaj yeem tiv thaiv kom tsis txhob muaj xim ntawm cov tshuaj oxidizable yooj yim xws li ascorbic acid, tso cai rau cov granulations rau cov ntsiav tshuaj yooj yim compressed thiab lwm yam ntau npaum li cas.EC tuaj yeem siv rau ntawm nws tus kheej lossis ua ke nrog cov dej-soluble Cheebtsam los npaj cov txheej txheem tso tawm cov yeeb yaj kiab uas nquag siv rau. txheej ntawm micro-particles, pellets thiab ntsiav tshuaj.
Ethyl cellulose tsis tuaj yeem yaj hauv dej, tab sis soluble hauv ntau cov kuab tshuaj organic, yog li EC siv hauv cov ntsiav tshuaj, granules ntawm nws cov nplaum nplaum. Nws tuaj yeem ua kom tawv tawv ntawm cov ntsiav tshuaj kom txo cov ntsiav tshuaj friability, nws tuaj yeem siv los ua tus neeg sawv cev ua yeeb yaj kiab los txhim kho cov tsos ntawm cov ntsiav tshuaj, kev sib cais saj, kom tsis txhob muaj qhov tsis ua haujlwm ntawm cov tshuaj dej-rhiab heev los tiv thaiv kev nkag mus ntawm metamorphic hloov pauv cov neeg ua haujlwm, txhawb nqa. kev ruaj ntseg ntawm cov ntsiav tshuaj, kuj tuaj yeem siv los ua cov khoom siv ntxiv rau cov ntsiav tshuaj tso tawm.

Daim ntawv thov
Ethyl Cellulose yog cov khoom siv ntau yam. Nws ua hauj lwm raws li ib tug binder, thickener, rheology modifier, zaj duab xis qub, thiab dej barrier nyob rau hauv ntau daim ntawv thov raws li nram no:
Adhesives: Ethyl Cellulose yog dav siv nyob rau hauv kub melts thiab lwm yam hnyav-raws li adhesives rau nws zoo heev thermoplasticity thiab ntsuab zog. Nws yog soluble hauv kub polymers, plasticizers, thiab roj.
Coatings: Ethyl Cellulose muab cov dej tsis muaj dej, tawv, yoog raws thiab siab gloss rau cov xim thiab txheej. Nws tseem tuaj yeem siv rau hauv qee cov txheej txheem tshwj xeeb xws li hauv cov ntawv sib cuag zaub mov, teeb pom kev zoo fluorescent, vov tsev, enameling, lacquers, varnishes, thiab marine coatings.
Ceramics: Ethyl Cellulose yog siv heev nyob rau hauv ceramics ua rau hluav taws xob siv xws li multi-layer ceramic capacitors . Nws ua hauj lwm raws li ib tug binder thiab rheology modifier. Nws kuj muab ntsuab lub zog thiab hlawv tawm yam tsis muaj residue.
Printing Inks: Ethyl Cellulose yog siv rau hauv cov kuab tshuaj raws li cov kuab tshuaj xws li gravure, flexographic thiab tshuaj ntsuam luam ntawv inks. Nws yog organossoluble thiab sib xws nrog plasticizers thiab polymers. Nws muab kev txhim kho rheology thiab khi cov khoom uas pab tsim cov yeeb yaj kiab siab thiab ua haujlwm.
